CHARLES H. WILLIAMS, JR., OF CHICAGO, ILLINOIS, ASSIGNOR TO CHICAGORAILWAY EQUIPMENT COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OFILLINOIS.

REINFORCED BRAKE-HEAD FOR SOLID BEAMS.

To all whom it may concern:

Be it known that I, CHARLES H. WILLIAMS, Jr., a citizen of the UnitedStates, residing at Chicago, Illinois, have invented a certain new anduseful Improvement in Reinforced Brake-Heads for Solid Beams, of whichthe following is a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, forming partof this specification, in which- Figure l is a top plan view, partly insection, of one form of reinforced head. Fig. 2 is a plan view of aslightly modified form of head. Figs. 3 and i are plan views, partly insection, of other modified forms of head.

This invention relates to a new and useful improvement in reinforcedbrake heads for solid beams.

Solid beams, whose ends are reduced by the removal of a portion of theweb or flange, suffer from torsional strains imposed upon them by theuneven wearing of the shoes. By reinforcing the head, as shown in theseveral forms of my invention illustrated in the accompanying drawings,the ends of the beam are prevented from being twisted around when thebrakes are applied, the extensions on the head not only giving the heada solid support on the beam and strengthening the head, but alsostrengthening the beam at its weakest point, to-wit: where the metal hasbeen cut away or removed. This cutting away of the metal at the ends ofthe beam, or reducing the depth of the beam at its ends, is madenecessary in certain types of brakes where the space in which the beammay be hung is limited.

In the accompanying drawings, I have shown, in Fig. 1, a bulb T-angle 1whose flanges have been cut away at the ends to permit the brake head 2to be inset. The brake head is secured in position to the web of thebeam by means of rivets 3 passing through its rearwardly extendingflange.

4 is an extension, preferably formed integral with the brake head,projecting inwardly from the side face thereof, in front of, and aroundthe front flange of the beam member. This extension not only gives amore extended bearing area for the brake head upon the beam and addsrigidity to Specification of Letters Patent.

the head, butalso strengthens the beam at the weakened ends.

In Fig. 2 I have shown a beam member in which a portion of the web atthe end has been removed, the flanged ends of the beam being pressedtogether. In this form, the lateral extension at from the brake head isconsiderably longer than is shown in Fig. 1, the extreme inner end ofsaid extension embracing the flange of the beam.

In Fig. 3 the extension t is shaped to reinforce the web of the beam andto also embrace the front fianges thereof, which flanges are cut awaysome distance inside of the head.

In Fig. & the front flange and web of the beam have been cut away on ataper, the brake head and reinforcing extension t being shaped toaccommodate this taper, the reinforcing extension embracing the frontflange and strengthening the weakened web of the beam.

I am aware that minor changes in the construction, combination andarrangement of the several parts of my invention can be made andsubstituted for those herein shown and described, without in the leastdeparting from the nature and principle of my invention.

Having thus described my inventiomwhat I claim is:

1. The combination with the main member of a solid brake beam, and abrake head having a reinforcing extension embracing a portion of thebeam member.

2. The combination of a flanged main member of a solid brake beam and abrake head having a reinforcing extension embracing the front flange ofsaid beam member.

3. The combination of a flanged main member of a solid brake beam and abrake head having a reinforcing extension embracing the web of said beammember.

4. The combination of a flanged main member of a solid brake beam and abrake head having a reinforcing extension embracing the front flange andweb of said beam member.

5. The combination of a beam member whose end is reduced or madeshallow, and a brake head having a reinforcing member for Istrengtheningthe reduced portion of the earn.

6. The combination of a flanged beam In testimony whereof I hereuntoaffix my member whose end 1s weakened by portions signature in thepresence of two Witnesses cut away for the purpose of maklng sald this26th day of May, 1909.
